As a device-driver developer, I want vemu to model BCM DMA controller, so that I can build and test firmware that needs sD/PCM/SPI/framebuffer DMA paths long before the hardware is in hand.

Why it matters

SD/PCM/SPI/framebuffer DMA paths

Summary

BCM2835-style DMA channels with control-block chains, lite/full channels, IRQs

Scope of work

Not present today. Deliver a behavioral model of BCM DMA controller. What it is: BCM2835-style DMA channels with control-block chains, lite/full channels, IRQs. Why it matters: SD/PCM/SPI/framebuffer DMA paths.

Current state

Status: Not implemented. Notes / evidence: Not present.

Blocked by 2

Fund these first - this work can't be completed until they ship.

Unblocks 4

Funding this also clears the way for the work below.
